Switch Configuration SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide
Media Speed
The Token-Ring media speed. Possibilities are 4 or 16 Mbps or Auto. When a
switch port configured with Auto discovers a connection to shared media, it will
open and insert into the ring. If the open returns with an indication, that the port is
the first station to enter the ring, it will close.
This algorithm is analogue to that of auto-sensing adapters, which dictates that an
adapter, which is capable of speed adjustment, must have some other station on the
ring (typically a server), from which it can sense the network speed.
If you want to have switch ports, which are attached to shared media, it is
recommended that you change the default media speed configuration from Auto to
either 16 or 4 Mbps.
Max Explorer Rate on Input
The maximum Explorer frame forwarding rate per second. Possible values are
Disabled
(default) or 0–5000.
Duplex Mode
The port operation mode. Possible values are, as follows:
•
Auto (A-HDX, A-FDX), the port determines the full-duplex or half-duplex
mode automatically.
•
HDX , half-duplex mode
•
FDX , full-duplex mode
Operation Mode
The port operation mode. Possible values are as follows:
•
Auto
The port is automatically detected, station mode.
•
Port
The port will simulate a MAU/LAM and allow NICs to connect directly.
•
Station
The port will simulate a NIC and connect to an existing MAU/LAM.
•
RI/RO
For SmartStack STS16-20R only, ports 19 and 20. Allows the switch to
connect to the RI/RO connector of a MAU or CAU.
➽ Note: If you change any configuration parameters of a connected port, the port will
close and reopen and you will lose all address information and statistics for that
port.
